Rated 5 out of 5 by from Mark 6 3-18 is My choice for a PRS optic! After trying one of these scopes out, I got rid of my Vortex Razor HD II 4.5-27 to buy the Mark 6 3-18 with a H59 reticle. It is lightweight, rugged, crystal clear, and offers a great warranty. The turret locks on the scope are genius, and help a ton. I had a chance to directly compare this scope in low AM & PM light conditions to the razor, and that poor Vortex couldn't perform with the Leupold Product. I shot with a 6.5 creedmoor all the way out to 1 mile using this scope, and I connected with my target. The return to zero on this scope is fantastic, and its always spot on when I re-install it on the gun. Great Optic, Great Warranty, what else could you ask for?!?!?!?!

Rated 5 out of 5 by from The Mark 6 is a robust rile optic! I'll never mess around with MOA scopes again! MRAD scopes are soooo easy, divide your distance by one thousand, then voila! 10 clicks will move your point of impact that many inches! (e.g. 300 yards = 10,800 inches, divide by 1,000 = 10.8 inches). Ten clicks will move the POI 10.8 inches at 300 yards! Obviously the scope is super high quality, it's a Leupold!

Rated 5 out of 5 by from Mark 6 1-6 Best 3-Gun Scope period. I have ran quite a few competitor optics for 3Gun, and after using the Mark 6 1-6 I will never shoot 3-Gun with another optic again. The CMR556 reticle on the First Focal plane is absolutely a wonderful tool to have. The red dot illumination on 1x makes it so you can hose targets as fast as you can pull the trigger.

Rated 4 out of 5 by from Great Scope But.... I highly recommend this scope. I used it on a M110 and really enjoyed it. However for military use I don't like the zero stop because of the need to be able to dial down when attaching NVD's. Also I would like to see a small knob incorporated on the zoom to make it easier to quickly dial in and out.

Rated 5 out of 5 by from Absolutley Stunning Optic The Mark 6 3-18 with the H59 Reticle is more than capable of getting you shooting out to a mile. The optical clarity, size, and weight of this scope makes it more than worth the money. The H59 Reticle is perfect for mil holds on strange yardages and holding in wind. I could not be happier with it.

Rated 5 out of 5 by from This has what I want I liked it so much I bought another one. When I bought it there was a promotion for a Leupold mat. It has been a year and I still have not seen the mat.

Rated 5 out of 5 by from Amazing Clarity I bought this scope 2 weeks ago and this is hands down the clearest rifle scope in my cabinet. Pesky wood chucks at 300 don't stand a chance.

Rated 5 out of 5 by from Leupold Mark 6 1-6 7.62 I bought this Scope over 2 years ago. It has out preformed in my opinion many manufacturers. The Mark 6 wasn't my first choice till I became a owner and now I plan on getting another. Love the 7.62 reticle. I have put it 300 RUM and scored 675 yard shots in Idaho with it also. Holds zero like a champ! Thank you Leupold!

100% Waterproof and Fog Proof

2nd Generation Argon/Krypton Waterproofing

While we still waterproof other optics with bone-dry nitrogen – technology pioneered by Leupold® – Select models feature our exclusive, proprietary Argon/Krypton gas blend. Its advantages are two fold: it nearly eliminates the effects of thermal shock, and the Argon/Krypton molecules are significantly larger than nitrogen molecules, reducing the diffusion of gases sealed inside your scope even more than our proven nitrogen technology already does. We pioneered riflescope waterproofing, and now with Argon/Krypton we’re exceeding the standards we set ourselves.

6:1 Zoom Ratio

A powerful 6:1 zoom ratio delivers crystal clear images from edge-to-edge throughout the entire magnification range. Many higher power scopes provide the best picture at each end of the zoom ratio, leaving the middle ranges weaker on clarity and resolution. The Leupold 6X erector system was engineered from the outset to provide consistently exceptional image quality across the entire visual field throughtout the entire zoom range. Twin Bias Spring Erector System features berylium/copper alloy leaf springs and 30% more holding force to withstand the most intense recoil and abuse.

Blackened Lens Edges

Blackened lens edges reduce unwanted glare and diffusion through the lens edges to provide better resolution, improved contrast and superior optical perrformance.

DiamondCoat 2

Exterior lens surfaces are treated with DiamondCoat 2™, an ion-assist lens coating, for higher light transmission and the greatest level of abrasion resistance we’ve ever offered. DiamondCoat already exceeds military standards for hardness and durability. DiamondCoat 2 offers unsurpassed durability and will prove its worth in the wildest places on earth. DiamondCoat 2 has the additional advantage of assisting in light transmission, for greater brightness, clarity and contrast.

Front Focal Plane (FFP)

The reticle magnifies along with the image, so you can estimate range at all magnification settings. These reticles are ideal in tactical situations, yet also provide greater accuracy of range estimation for hunters and target shooters.

Auto-Locking Pinch and Turn Adjustment: Leupold's exclusive locking adjustment that unlocks when you grip it to adjust. With a tactile revolution counter. Confidently adjust windage and elevation while preventing accidental changes in the field. (1/10th mil per click-- 20 mils/2 revolutions total.

Xtended Twilight Lens System

Now your hunt can reach further into the twilight than ever before possible, with our exclusive new Xtended Twilight Lens System™. It goes a step further than even the Index Matched Lens System®, using Leupold’s® index matched glass with wavelength specific lens coatings designed to optimize the transmission of low-light wavelengths. When most scope manufacturers quote percentage of light transmission, they usually mean at 550 nm, the green wavelength where the human eye is most sensitive. The challenge is that in twilight conditions, green light disappears and blue/violet light takes over. Your eye is already handicapped when it comes to seeing the blue/violet spectrum, and if your scope is cutting too much of it out, soon you won’t be seeing anything. The Xtended Twilight Lens System places extra emphasis on matching coatings to glass indices to achieve the best possible transmission of the blue/violet spectrum, without sacrificing the color balanced light transmission across the visual spectrum of the Index Matched Lens System. When we combine that with superior computer-generated optical design, lead-free lenses of unsurpassed clarity and quality, and 100 years of manufacturing excellence, you have a scope that gives you the details of low-light scenes in greater definition and luminance than any other scope in the world.
